TosaZZ whome'tmayiconcern:

Bea known that I, DAVID C. HoT'rELL, a

citizenof the -United States, residing near Meeker, in the county. of Rio Blanco and State of Colorado, have invented certain new and useful Improvements in Ditching-Machines, of which the following is a specification.

This invention relates to ditching machines and more particularly to ditch. cleaning machines and it hasifor. its object the provision of an improved... device. of this character constructed in such manner as to rovidea ditch of novel shape asw ill here lnafter be set forth.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawing,

Figure 1 is a lan view of a ditching machine constructe in accordance with the invention.

Fig. 2, is a transverse vertical section through the landside upon line 22 of Fig. 1.

Fig. 3, is a transverse vertical section ghrough the mold board upon line 33 of Fig. 4', is a side elevation looking toward the mold board.

Fig. 5, is a view of the mold board illustrating the position that the mold board assumes when the ditching machine is traveling in one direction, and

Fig. 6, is a like view illustrating the position that the mold board assumes when the ditching machine is traveling in the opposite direction.

Like numerals designate corresponding parts in all the figures of the drawing.

Referring to the drawing 5 designates the landside the rear end of which is slightly concave in form. A mold board 7 has its forward end pivotally connected to the landside by loops 8 which pass through elongated openings 9 formed in the mold board. These openings are of such size as to permit a slight rocking movement of the mold board with relation to the landside to thereby permit the mold board to move vertically out of the plane of the landside in either direction, for a purpose which will be hereinafter set forth.

A clevis 10 is pivoted at 11 between ears 12 formed at the front end of a T-bar13, the latter extending longitudinally along the rear'face of' the land side and being secured thereto and serving to stiffen and strengthen the same as well as to providea point ofattachment: for the clevis. A rod l l is provided with an off-set end 15 that is adapted to engage in anyone ofthe open- Patented Sept. 3%, 1919;

ings 16 of the mold board7 and the opposite end of this rod is adapted to engageln opening 17 of the clevis 10.. Links 18 and 19 are, pivotedgat.20and 21 to the landside and mold board respectively and the link 18 is provided with a plurality of openings, '22 j by which said link may be adjustably connected to the. links 19 through; the .medium. of a pin 23. This construction permits the mold board to be adjusted toward and from the land side to thereby adapt the device to clean ditches of varying widths. By referring to Fig. 3 it will be seen that the mold board is concave in cross section and that at its front end (see Fig. 4) said mold board is tapered to form substantially straight edges 24: and 25. The land side is tapered so that at its point of attachment to the mold board it is narrower than the mold board and this arrangement combined with the concavity of the mold board results in the provision of a plow-like structure which imparts a rolling movement to the earth, when in action, that very effectively dislodges the dirt and discharges it from the ditch. Furthermore, the formation of a mold board of this shape and the mounting of such mold board by means of the elongated openings 9 and loops 8, provides a structure which will clean a ditch of the shape illustrated at 26 in the drawing. In other words, such structure will clean a ditch having a flat bottom.

Devices of this nature heretofore proposed have been adapted to clean only V shaped ditches, but by virtue of the structure herein shown and described one of the edges 24 or 25 will lie in contact with, and scrape the bottom of a ditch when the machine is traveling in one direction and the other of said edge will automatically move into position to clean the bottom of the ditch when the machine is turned over and is traveling in the opposite direction.

It is to be understood that the invention is not limited to the precise construction set forth, nor to the proportions illustrated, nor to the particular type of pivotal connection shown, for it is manifest that it is well within the range of mechanical skill to center' of the mold board and means for vary these elements without departure from the basic principle involved which is that of a providing a mold board, the opposite edges of which are operable when the machine. 1s-

traveling in opposite directions and which iscapab-le of such rocking movement above and below the plane of the landside as to permit it'to assume the proper: position to 5 carry out the objects set forth. 7

Having described my invention what I loosely pivotally connecting the landside Copies of this patent may be obtained-1'01- flver cents each, hy'addressing the Commissioner of :Patents; 1

and the mold board in such manner as to permit the mold board to move vertically with respect to the landside ineit'her direction, to such an extent as te cause thatcut away portion of the mold board which lies towardthe bottom to lie substantially hori- ZOhtitlQ V V 2. The combination with a landside, of a V mold board the latter being cutaway adj acent its front end to form working edges. which lie at an angle to the longitudinal center of th'e'mold board, said mold board being concavo convex in cross section and being" wider than the lands ideat itspointof aft-YT. tachment thereto, and means Jforiho'lding the moldboard invarying positions of' an? gular adjustment with respect to the land i side.
